Don't Know The Problem

[Trance]

Okies so i tested my graphic card and thats not the problem coz it works.

So here is the story then hopefully u guys can give me your imput to try and figur out the problem of how much is gonna cost.

So a little while ago i was watching something on youtube when my computer turned its self off, not like shutting down.. it just went off.
So i turned it back on. and what was happening it would start to boot up like start for 3-5 seconds then it would turn its self off. So i left it for about 10 mins doing that.. then it would boot up 100% and stay on but there was nothing on the screen. when i say nothing i mean. " You know when u guys shut your computers down for the night, and your monitors go from a green light. to a amber light.. well thats what was happening with mine.

So when i took out the graphic card and it booted up streight away.. thats why i thought it may i have been the graphic card.. but that dose not seem to be the problem.

so could it the prosessor, or the motherboard.or maybe the hard drive

i'm praying its not the motherboard..

so if u guys have had simalar experainces and u think u may not the problem.. please post and let me know.. cheers!
